Estimate of equilibration times of quantum correlation functions in the thermodynamic limit based on Lanczos coefficients
Jiaozi Wang, Merlin Füllgraf, Jochen Gemmer
We study the equilibration times of local observables in quantum chaotic systems by considering their auto-correlation functions. Based on the recursion method, we su…

Evidence for simple "arrow of time functions" in closed chaotic quantum systems
Merlin Füllgraf, Jiaozi Wang, Jochen Gemmer
Through an explicit construction, we assign to any infinite temperature autocorrelation function a set of functions . The construction of from requir…
